Gastric cancer is a common malignant tumor of digestive system. The most obvious symptom of gastric cancer may be pain and discomfort in the upper abdomen. But this symptom is not typical, that is to say, other digestive system diseases, such as gastritis and gastric ulcer, may also have this symptom. Therefore, symptoms alone cannot diagnose gastric cancer. Once there are uncomfortable symptoms, we must further check them. We cannot directly prescribe some medicine, so it is easy to delay the condition. Gastric cancer is diagnosed mainly through gastroscopy and pathological examination. After the diagnosis of gastric cancer, it also depends on whether there are metastatic lesions in other parts. If there is no metastasis and the patient's physical condition allows, radical surgery should be considered.? The operation usually involves total gastrectomy and partial gastrectomy. After the operation, it is necessary to cooperate with systemic treatment. Because gastric cancer is also a systemic disease, simple surgery cannot achieve the effect of radical cure. Unless it is very early, postoperative adjuvant chemotherapy is required, at least 4-6 courses.
